SOCKET WRENGE.

Application filed Auguat 21, 1925. Serial No. 51.6%.

This invention relates to wrenches and has for its object the provisionof a device having a socket head mounted on a shank by a universalconnection so that a socket.

may be operated at any angle direct with a sleeve slidable on the shankand head for lockingthe head rigidly to the shank whereby the device maybe employed as a straight wrench.

Another object of the invention is the provision of a wrench having aremovable handle bar'mountedin a head, which; is adapted to be removablyconnected wlth the shank of the Wrench.

This invention will be best understood from a consideration of thefollowing detailed description, in view of the accompanying drawingforming a part of the specification; nevertheless it is to be understood0 that the invention is not confined to the disclosure, beingsusceptible of such changes and modifications which shall define nomaterial departure from the salient features of the invention asexpressed in the appended claim.

In the drawings Figure 1 is a view in elevation of a wrench constructedaccording to the principles of my invention,

Figure 2 is a view in elevation of a shank and universally connectedsocket head Figure 3 is a View in elevation of the sleeves for thewrench,

Figure 4 is a view in elevation of head for removably connecting ahandle bar to the shank,

Figure 5 is a fragmentary view in elevation of the lower end of thesocket wrench showing the same in operative position through theuniversal connection,

Figure 6 is a view in elevation of a modified form of the wrench used asa straight wrench, and

Figure 7' is a view in elevation of the wrench shown in Figure 6, withthe universal connection in operative position.

Figure 8 is a bottom plan view of the head shown in Figure 4:, and

Figure 9 is a bottom "plan view of the socket employed with the wrench.

Figure 10 is an enlarged detail sectional view showing the springpressed balls and transverse passages and recesses there or.

Referring more particularly to Figure 6 2, the shank 10 is providedhaving an en- 'larged lower end 11 from which projects a may have ahexagonal opening 21 to re- -as a straight wrench. When sleeve is movedpair of rigid integral ears 12. These ears are perforated to receive apin 13 upon which is pivotally mounted a block 14 adapted to oscillatebetween the ears 12. A pin 15 is mounted on the block 14 and adapted tobe received by perforations in a pair of ears 16 carried by a sockethead 17. This socket has a pair of spring pressed balls-l8 as shown inFig. 10, mounted in a transverse passage, which are adapted to projectfrom the ends of the passage and engage recesses 19 formed on the innerwall of the socket 20. This socket is of the usual type and ceive asimilarly formed nut orbolt head. The sockets, as is well known, are ofvarious shapes and sizes for the. engagement of bolt heads and nuts ofvarious sizes and shapes. A swingably mounted block and supports for theswingably mounted socket head 17 permits movement of the head 17 in apluralit of difi'erent directions so that the wrenc may be employed asshown in Figure 5, as a universal wrench.

The sleeve 22 having a knurled portion 23 is slidably mounted on theenlarged portion 11 of the wrench and is limited in its upward movementby an annular shoulder 24 and in its lower movement by an annularshoulder or flange 25 carried by the socket head 17- This sleeve has onits inner wall a pair of recesses 26 and 27 which are adapted to engagethe spring pressed ball 28 carried by the enlarged portion 11 of theshank 10 (see Fig. 10); so that when the sleeve is moved to itslowermost position, recess 26 engages ball 28 and locks same in place sothat the Wrench may be operated to its uppermost position against theshoulder or flange 25, the recess 27 on the inner wall of the sleevewill engage the ball 28 and lock said sleeve in osition.

A second andlonger s eeve 29 is mounted on the shank 10' and has aknurled portion 30. This sleeve is fitted on the said shank andterminates adjacent the upper end of a collar 31 on the shank. Beyondthe collar 31 is provided a hexagonally shaped ortion 32 adapted to beinserted within a hexagonally shaped passage 33 in a handle head 34.This head is provided with a transverse passage 35 through which isinserted a handle bar 36 and a spring pressed ball 37 is mounted in apassage 38 longitudinally of the head 34 and is adapted to frictionallyengage the handle 36 and prevent displacement of the handle from thehead. The lower end of the head is provided with a recess 39 adapted toengage the sprin pressed ball 40 in the hexa onally shape ortion 32 ofthe shank 10 or locking the iiead against displacement from said shank.Referring more articularly to Fi res 6 and 7 a shank 41 has anintegrally ormed head'42 provided with a transverse passage 43 throughwhich is adapted to be inserted a handle 44. A sprinig pressed ballmounted in a longitu inal passage in the shank 41 is adapted to engagethe handle bar 44 and prevent displacement. of either bar from the head42. The lower end of the shank is identical in construction with theconstruction shown in Figures 1' to 5 inclusive and in which a sleeve 22is slidably mounted upon an enlarged portion 11 of the shank, and whenthe lower portion, as shown in Figure 6, is ada ted to convert thewrench from a'universal evice, as shown in Figure 7, to astraight'wrench, as shown in Figure 6. The sleeve is adapted to belocked in place by a spring pressed ball 28 shown in dotted lines inFigure 6 and similar to ball 28 in Fig. 10, when the sleeve is in itslowered position, while said ball is adapted to engage the recesses 27similar to recesses 26 and 27 in Fig. 10, when the shank is elevated,

and disclosed by Figure 7 permitting the p wrench to be actuated as auniversal socket wrench. The enlarged portion )1 is rovided with spacedears carrying a bloc 14 integrally mounted on a pin 13 while a sockethead having cars 16 pivotally connected with the block 14 on the lower,end of the head is adapted to be received in a socket 20.

What I claim is:--

A wrench comprising a shank having spaced ears at one end, a blockpivotally I prevent displacement of the handle from the head, and asecond and long sleeve mounted on" the shank above the first namedsleeve and prevented from displacement from said shank by the handlehead, said last named sleeve adapted to serve as a hand hold when thesocket head is applied in variousangular positions. r
